Description:Ramaria maculospora Petersen, 1985. Mycologia, 77: 912.
Fruit bodies up to 12 x 8 cm, irregularly shaped but often broadly ellipsoid in outline. Stipe up to 40 x 40 mm, stout, rounded at base but often mycelioid and involving substantial substrate when picked, soft, smooth but not glabrous where protected, beset with numerous abortive branchlets, white to ivory color where protected ("ivory yellow," "pale ochraceous salmon"), not changing color on bruising or handling; flesh white, solid, soft, often watery and marbled, especially in wet weather, drying soft and friable; abortive branchlets offwhite where protected, concolorous with branches where exposed. Major branches three to several, ascending but not strict, flattened, pale tan ("pale ochraceous buff") when young, fleshy tan ("pinkish buff," "ochraceous buff") by maturity, occasionally weakly vinescent around soil particles; branches in 3-5 ranks, open, spreading, usually flattened, concolorous with major branches; hymenium often unilateral; internodes lengthening acropetally ontogenetically; intemode ratio diminishing rather abruptly at maturity; axils rounded to lunate; apices minutely digitate to densely cusped when young, abruptly white to pale yellow ("warm buff"), gradually becoming concolorous with upper branches ("light ochraceous buff"), in age often clawlike, flattened; abortive branchlets off-white where protected, concolorous with branches where exposed. Odor weakly fabaceous to weakly sweet; taste negligible to mildly bitter.
Macrochemical reactions: NOH, KOH: obscurely copper colored; IKI: negative; PYR, PHN, GUA, FCL, ANW, ANO: positive to intensely positive.
Tramal hyphae of stipe 4-15 µm diam, hyaline, clamped,
thin-walled, easily collapsed (and often appearing refringent, like gloeoplerous hyphae); ampulliform inflations very rare, abruptly onion-shaped, thin-walled, ornamented; gloeoplerous hyphal segments rare, short, usually juxtaposed to septa. Tramal hyphae of upper branches similar to those of stipe, 1.5-15 µm diam; ampulliform inflations not observed; gloeoplerous hyphal segments as above. Hymenium thickening; basidia 43-55 x 8-9 µm, clavate, clamped; contents homogeneous, appearing empty after spore discharge; wall thin, easily crumpled; sterigmata 4, straight, apical, spindly.
Spores 8.3-10.1 x 4.7-5.4 µm (E = 1.64-2.08; Em = 1.79; Lm 8.95 µm), ovoid to broadly ellipsoid, conspicuously roughened in profile; contents dark, sludgy, with dark ochre amorphous inclusions; wall up to 0.2 µm thick, not thinner distally; hilar appendix prominent, often beak-like, gradual, with a small cyanophilous struma; ornamentation of scattered, strongly cyanophilous, discrete low warts.
Commentary
The description above was abridged from the original, which was based on southern Appalachian specimens. Nova Scotian material differs in the following ways: (i) slightly longer spores (for southern specimens: 8.3-10.1 x 4.7-5.4 µm; E = 1.64-2.08; Em = 1.79; Lm = 8.95 µm); (ii) perhaps slightly more salmon branch colors (although only one specimen was gathered); and (iii) vinescent spots on branches. These differences might justify a separate variety, but carefully annotated collections from the mid-Appalachians are needed to test their variability.
The organism reported by McAfee and Grund (1982) as
R. secunda is probably R. maculospora. The descriptions of the two taxa agree in most respects. Most authors (Corner 1970; Marr and Stuntz 1973) agree that R. secunda should be reserved to represent a striate-spored taxon, which has been placed in synonymy under R. holorubella or R. botrytis.
